And money. Money is a huge factor in bringing this series back. It's a niche market within a niche property. Even if Coto comes back can the cost be justified?
The sets should be cheap to build now. LCD panels don’t cost much anymore compared back in 2001. With that being said, if it’s the NX-refit, then maybe the interiors get a redesign in the process of the stardrive section being added, so that there is no worry as to whether a rebuilt NX bridge/sickbay/mess hall/engineering section is accurate. Maybe take to opportunity to redesign the shuttlepods, phase pistols, and torpedoes. Maybe take out the transporter. Maybe add a holoprojector for various bands to be played.
Not sure what it would cost to contract the cast. And depending on who comes back would likely impact whether a revival is live action or animated, as well as whether its set directly after S4, or decades later. And that not even taking into consideration as to whether Enterprise spent a great deal of time as the first timeship immediately after “Terra Prime”, to explain why the cast looks a little older if we start from when the show left off.
If ENT is brought back, and there are concerns about it being niche, it does mean that every season should be self contained and not leave things open ended as a finale. Unless they intend to do a movie or two afterwards.
I do think its going to happen at some point. There are NX-Refit model kits, as well as it being featured (both exterior and interior) in the Ships of the Line 2021. There is possibly a plan for it to end on onscreen at some point.
Let me float a slightly different idea.
What Admiral Archer Did Next.
Might be the NX-01 with a new crew, might be a PIC style thing. What I would really like to see is... the ads for ENT said of Archer, "This was Kirk's hero". I'd like to see that story, that we didn't quite get in ENT. With the advances in storytelling, it could be quite good.
Admiral Archer being Kirk’s hero should definitely be explored more.
I have no interest whatsoever in revisiting old characters, precisely because I'm probably not going to like someone else's take on the character 20 years after the fact.
The audience is larger than one or two people. Just because you might not like the new portrayal does not mean other viewers will not.
The problem is that it's usually not up to the actor as to how the character is portrayed; it's up to the writer. Despite what she says that she wants, if she's hurting for acting gigs and the only thing biting is to play 'scared Hoshi' again, that's what she's going to do.
And if the actor doesn’t like the portrayal in the script, then the actor can refuse the role. And while it might compel TPTB to simply recast the role, it seems like it would be far simpler to address the actors concerns instead of recasting them altogether.
